PostgreSQL for Mediawiki

I have patched the current mediawiki CVS version to include PostgreSQL support. I keep it in my personal svn and will put here snapshots periodically.

Since the mediawiki developers not only refuse to help getting postgres support in, they also try to make it as hard as possible for anyone else to provide patches. E.g. they insist on using sql syntax that only mysql supports, not allowing syntax that both would accept (and maybe even oracle)
If anyone is willing to feed them in with small parts, let me know we can probably work together and you can use my ideas here as a starting point. The main problem still is that in complete mediawiki the usage and escaping of blobs isnt properly done, so postgresql beeing a bit more strict on how to use bytea might need some more tweaks to get rid of the "already encoded" hack.

Note that for the search to work, you need to have a proper working tsearch2 install (comes with the contrib part of postgresql)

SMTPMAP

Currently, smtpmap is dead. As nmap does a quite ok job, that seems to fit the needs of most of the users, smtpmap will not be developed anymore, unless there is enough public demand.

If you want to test the latest version, it can be downloaded here:

Active Projects

MemAlyzer

A quite new program to better visualize memory usage of your program. A bit inspired by massif, windows defrag and a tool I use at work internally (memtag).

Planned Projects

N.N.

Yet another apache log analyzing tool. Should be quite similar to webalizer and awfull, but with the features and changes that I like. It should also do some sophisticated caching of the data, so that subsequent runs are faster. I think this could be an intresting project to use boost::serialization for.

Status:Planning

N.N.

This project will create a program to help in digital enhancement of amateur astronomy images. It will have an intuitive to use graphical userinterface (based on Qt) and can be extended by various plugins. The most important features will be: Preliminary name: viss (Versatile Image Stacking System), basierend auf viss (Versatile Image Processing System)

Status:Planning

IW Mapper

The IW Mapper is a qt application whose primary purpose is to maintain the database information for the iWear WLAN Localisation subsystem. Nevertheless you will be able to maintain the standard Localisation subsystem too and import different maps and display different informations on it. Maybe in the far future we will be able to do limited navigational analysis.

Status:Alpha

SpamFix

SpamFix is a fast spamfiltering program, based on a bayesian approach. The project is currently dead, with only partly existing sources. It will be resurrected as soon as enough resources are available and together with the iWear Project basics will be built on a completely new source base.

Status:Reengineering

N.N.

While commercial tools are hard to use and open source tools lack flexibility, there does not seem to be a good apache weblog analysing tool around. This should be a very modular tool that can do incremental runs and display thorought information about everything it can get. Plugins should make it possible to add data gathered from javascripts that collect settings like resolution etc.

Status:Idea

N.N.

While the commercial Programs sometimes do a quite good job at OCR, there is no free tool that has the same quality. Worse, I believe that you can do far better than the commercial tools, with a few new ideas. So the idea is to write a good OCR tool, that has good recognition quality as well as a good interface that can really good help teaching and improving the program.
While doing that, Im sure the development process could benefit from a simulatenous developement of goof handwriting recognition programs. Plugged into a "standard" OCR tool, it can enable to recognize mixed documents. It should be able to work from bitmap data as well as vector data (path of the pen).
Really good would be too, to be able to process heavily distorted letters, where a prerequisite would be to automatically find them in an image. That way we could have a really good automatic tool, that can extract text out of images for searching.

Google Earth offers a huge amount of data with location information. While most of the data is merely used for just browsing the world, some of it could be put to some better use. This software shall take the google information about distribution of webcams, and from that on it shall be able to display multiple webcam livestreams. Of course not only the webcams of google, but also manually entered should all be able to be displayed at one, in a configurable environment. Multiple windows, across multiple screens, or even multiple x-servers should all display those. To increase performance, all those other displays should run client applications which just are controlled by an master app, but decode their data themselves.
One possible application could be the search for tornados in areas with a high webcam density. A future version of this program could be able to put an overlay grid over the visible data, so you can exactly determine coordinates of what you see. This shall be an external library to be able to be used by other programs too, so you could do that with still images, other video feeds etc. pp.
Later versions could be able to produce overlays for maps, so we can see what is visible within the camera, also with different colors so we know how good. Single videos shall be controllable all in their zoom factor, or you could control to cut-off a little part of it. It could be semi-automized to draw a track of something along the map. Maybe with multiple input vectors, all of which do some voronoi tracking and then display a full track. Also some movement detection could be put in, so that it triggers alerts when it sees something big moving.

Status:Idea

N.N.

Yet another decompiler for C++. Of course its impossible to really decompile a program from binary to C++ back, but we can try to do so. This project shall do it with a GUI and some project files giving the user the possibility to interactively support the system, and maybe help it learning what certain things mean. The user should be able to give names to local variables, adjust strange constructs to be switch/case blocks and let the decompiler rearrange later accesses to these variables etc.

Status:Idea

N.N.

Beagle (the open source variant of googles desktop search) could need a bunch of plugins. As well as some improvement in its speed, it could outperform google. Together with some windows clients as well as some central database and user rights, it would be a perfect environment even in company networks.

Status:Idea

N.N.

A compression tool to experiment with different compression algorithms. The goal should be a very good overall compression. We should incorporate all the ideas to improve LZW (variable code length, variable dictionary length, fifo dictionary filling, dictionary entries deleted before resizing etc.) along with a good way to encode those code indices so that a following arithmetic coding pass will work better. Optionally include some other encoding scheme, or even invent some new. Maybe we can also introduce some burrows wheeler pass, that will help creating codes better optimizable in the LZW pass.

Status:Idea

N.N.

Yet another GUI/Widget library. Why? Because I do believe that the current existing ones are fundamentally flawed in various ways. This list applies not to all of them, but all of them have at least one of these flaws. As a first target the library shall implement all features as X11 client. Various features not available on other ports shall be clearly notified by #defines, where possible workarounds should be built so that in the best case, no #ifdef based decision in the user program is needed, and maybe the program just behaves a little bit differently at runtime.

Status:Planning

N.N.

A tool to automatically determine the performance of a set of compression tools. With a web displaying, similar to http://compressia.ca

Status:Planning

Small Tools

During the time, I developed some small tools that I will make available here.

nmbsub2

At the end of the 1990s there were very much windows systems with open shares. I developed, and rewrote this tool to scan for such open shares in a given subnet, to count the amount of open systems, and its change over time. Unfortunately due to repeated hard disc failures, I lost the original statistics. All I can remember is, that due to changed default settings in Windows XP SP1 the number of open system keeps decreasing. Still today there are some systems open, though I think they are below 1% here in germany. It could be different in areas where more Windows 98 or other systems are available.

Note that it searches a whole 24 Bit network, given without the last element of the IP. You can change the script to allow faster scanning, while parellelizing more processes. You should also run the tool in an empty directory, as it will create a file for each found host.

searchjpeg.cpp

After some unfortunate deletion event on my digital camera, I developed this tool. While all the file recovery tools only find complete files, if at all, this tool can search for jpeg fragments, as long as the header is intact. This way I was able to at least get a few pieces back of my images. Im currently trying to improve it, so it can be used on block dvices too, so that it could be used as some forensics tool for searching harddiscs.
